I was doing some simualtion with the time variant sigma and current using FDTD. The problem is that the sigma is larger than 1 { my time step is 1 ns,can not be smaller than this value } which will cause the coefficient of the iteration for E fields
factor = epsi-sigma*dt/2 negative, then cause osillation of my simulation.
Are there some gurus can give me some advice on how to deal with this issue.
Thanks
